Url corruption when ":/" present

[coderaiser]

Why are you replace lines: :/ to :// in urlJoin of common.js?

It corrupt work of join-io which uses such urls:

<script src="/join:/lib/client.js:/lib/util.js:/join/join.js"></script>

@coderaiser its meant to handle cases where http://whatever.com turns into http:/whatever.com. This is a naive urlJoin since it fails on this case, it should be more specific to the post http. I would love a PR to fix this if you can turn this into a test case :)

The thing is no http:// string is present on args. Here is example

args = [ '/',  '/iocmd/join:/modules/format-io/lib/format.js:lib/client/directory.js:/join/join.js' ] 
retSegs = [ '/iocmd/join://modules/format-io/lib/format.js:lib/client/directory.js://join/join.js' ]

@coderaiser Yes I understand. I was mentioning thats why it exists, Im not saying its correct. The code here needs to be smarter to handle the case you are mentioning.
